Common Problems in Assembly of Sichuan Roots Blower


Sichuan Roots blower is a centrifugal impeller driven by a motor to rotate in the opposite direction for exhaust and breathing. Because of the uniqueness of the equipment, several aspects of the equipment need to be paid attention to in the installation.

During the installation of Sichuan Roots blower, the belt reel of the link point motor should be in a plane. If it is not careful here under assembly, it is not easy to cause common faults when cheated equipment is running on a plan, so this is also very important.


Second, the inlet and outlet of Sichuan Roots blower cannot enter articles, and the throttle valve of the blower cannot be installed reversely. If the throttle valve is assembled upside down, the pipeline pressure will be too high, and the centrifugal impeller and the electric motor will reverse. Once the blower is reversed, the Roots blower will be destroyed.


When the equipment arrives at the user's site, first pay attention to the assembly of the motor when installing the machine. The forward and reverse rotation of the motor should be installed reasonably. The motor cannot be reversed. Second, when the motor is used for steering, the motor cannot overcurrent. Check whether it is overcurrent. It can be detected by multimeter. Second, the indispensable phase of the motor needs overvoltage protection of the equipment power supply during the equipment process, better to achieve the safety and reliability of equipment and power protection and other functions


The above are some problems that need to be paid attention to when Sichuan Roots blower is installed and applied. Centrifugal blower belongs to consumables. Proper maintenance will also increase the service life of the equipment. Timely inspection and immediate daily maintenance must be carried out when installing and applying!


basic principles of sichuan roots blower:


Sichuan Roots blower is a kind of positive displacement fan. There are two kinds of three-blade centrifugal impellers rotating relatively in the space enclosed from the shell and wall plate, because each centrifugal impeller adopts involute gear, or the envelope line of the outer rotating wheel line is the impeller processing line, the three leaves of each centrifugal impeller are completely consistent, and the two centrifugal impellers are completely the same, which can reduce the difficulty coefficient of production and processing. Centrifugal impeller in the production of the use of numerical control machinery, to ensure that the two centrifugal impeller in the pitch will not change the premise, regardless of the two centrifugal impeller rotation to which position, can maintain a certain small gap, to ensure that the gas leakage within the allowable range.


The two centrifugal impellers rotate in opposite directions. Considering that the gap between the centrifugal impeller and the impeller, the centrifugal impeller and the shell, and the centrifugal impeller and the plate is very small, the air inlet forms a vacuum environment. The gas enters the air inlet cavity under the action of atmospheric pressure. Subsequently, the two leaves of each centrifugal impeller form a sealed cavity with the wall plate and the shell. The air in the air inlet cavity is in the process of rotating the centrifugal impeller, the sealed cavity formed by the two leaves continuously extends to the exhaust pipe cavity, and because the centrifugal impellers in the exhaust pipe cavity are toothed with each other, the air between the two leaves is squeezed out, so that the gas is continuously transmitted from the intake pipe to the exhaust port, which is the whole working step of the Roots blower.
